"Dr Sayeg and his team always take great care of me at my regular visits.  I feel welcome when I arrive and comfortable throughout me visit.  I've been going to for regular visits for so long that I can't remember how many years it's been, and I even scheduled a cleaning when I was in town on vacation after moving out of state for a year!They are always looking for new ways to make my experience a good one, and on my last visit I received a complimentary paraffin wax on my hands while I got my teeth cleaned.  Now that's service that goes above and beyond and strives to make a person comfortable.  I have referred many friends to Dr Sayeg and they continue to be his client still, so if you are looking for a great dentist and dental experience contact the office today."



"I really enjoy coming to this dentist office. I actually used to go to one near my house but my coworker recommended this one since its close to my job. I needed something closer to my job so I can go before or after work. I came here originally for a pain that I've had in my mouth for months that my previous dentist couldn't find. They welcomed me with open arms and tried to diagnose the problem. Dr. Sayeg is very patient and friendly. He has been on a quest to find out where the pain is coming from. I'm confident that we'll get to the bottom of it soon. His hygienists are fun and funny. That helps the cleaning experience to go by quickly. I always feel comfortable when I go into the office. They're on time with my appointments and their hours are convenient for my schedule. They connected me with my awesome orthodontist (Dr. Kaplan) and I'm excited that by this time next year I'll have the smile I've dreamt about for a long time."
